Plano-Convex Cylindrical Lens TJFSGXPTZM2010027

Plano-convex cylindrical lenses combine a plane and a convex cylindrical surface to control light in one direction, such as focusing, divergence, or shaping, with little effect in the perpendicular direction. This one-direction optical action supports laser processing, optical inspection, and beam shaping. The plane surface is described as not deflecting transmitted light; the convex cylindrical surface resembles an outward-curving part of a cylinder and focuses or diverges light in one direction. Unlike biconvex cylindrical or plano-concave cylindrical lenses, only one surface is curved, giving a simpler structure and clearer function. Available specifications: size (mm): 5*5-20*20; EFL (mm): 10-1000; center thickness Tc (mm): 2.0-12.0; edge thickness Te (mm): 1.0-3.0; radius R1 (mm): 5.0-500.0; materials: optical glass, calcium fluoride, zinc selenide, silica, etc.; coatings: AR, high-reflective, bandpass, beamsplitting, etc. Note: the following table shows only some biconvex lens sizes; contact us for others. Custom sizes and coatings are supported. One-direction focusing makes plano-convex cylindrical lenses useful for beam-shape control, line generation, and aberration correction. Function | principle | applications: One-direction focusing | the convex cylinder refracts along its curvature and converges light into a line | laser scribing, beam shaping. Line-source generation | converts a point source into a line rather than a spot | barcode scanning, optical inspection. Beam shaping | converts circular beams to ellipses or compresses/expands one direction | optical coupling, imaging optimization. Aberration correction | corrects astigmatism or coma along one direction | compound optical-system design.
